Because the overall density of a can is less than the density of water, a solid aluminium pole has a density greater than water
The aluminum foil is less dense than the water which makesit float. Aluminum foil is not less dense than water. It is more dense. The reason that aluminum foil floats is that the surface tension of the water will hold the sheet of foil. If you still think that the aluminum foil is less dense than water, try floating a roll of foil in a bucket.
Aluminum has a density of 2.7g/cc which is higher than that of water (1.0g/cc) and ordinarily would sink; if the can was empty and thus (like a boat) able to displace more weight in water (by virtue of its volume) than its own weight, it could then float. However, if it was filled with water, its overall density considering both the metal and the container's content, would be higher than water, and it would sink.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
If it was solid, no it would not float in water since it would displace less water than its weight. In other words, the density of aluminium is higher than the density of water, and denser objects will sink. If it were a hollow sphere and displaced more weight in water than its own weight, it could float - but that would not be by virtue of the density of aluminum, it would be because it was hollow.
There are tents designed to Float in water. But not all tents designed to float.
yes
Shape the aluminum to look like a boat, so it displaces enough water to float. The force supporting the aluminum is the buoyant force. It is equal to the weight of the volume of water displaced.
A thin aluminum foil can float on water if placed carefully flat on the surface because of the surface tension of water. If you were to submerge it, the foil will sink.
Yes
A solid bar of aluminum would not float, since its density (almost 3 grams per cc) is greater than that of water (1 gram per cubic centimeter). For an object to float in water, its density would have to be less than 1.0.
Yes, if is empty.
Aluminum.
Answer #1: float.==========================Answer #2:The density of aluminum is 2.7 gm/cm3.So, just like steel, if you shape a piece of it just right so that it displacesenough water, you can make it float. But a lump of it will sink in water.

Generally speaking, a denser substance will sink in a less dense substance. Assuming standard temperatures, since aluminum has a density of about 2.7 grams per cubic centimeter and water only has 1 gram per cc, aluminum would sink. A thin aluminum foil could float by virtue of the surface tension on water (but if submerged, will sink). An aluminum boat would float because it displaces a greater mass of water than its own weight. An aluminum block could also float on a liquid of higher density.
Wood will. A solid block of aluminum will sink. Things float when their density is less than water. There are some woods that sink.
